Overview
If you have just switched on a Google or Meta campaign and you are refreshing the dashboard every hour, you are not alone. It is one of the most common questions trade business owners ask when they start paid advertising: how long do paid ads take to work? The honest answer is that it depends on the platform, but there is a real, evidence backed timeline behind both. Google Ads can start showing impressions within hours of approval, while Meta typically needs about a week of steady delivery before its algorithm settles down. Neither platform hits its stride overnight, and understanding why will save you from pulling the plug too early.
This guide breaks down exactly what happens in the first days, weeks and months of a Google Ads or Meta Ads campaign, so you know what is normal, what is a red flag, and when you should actually expect a return on your spend.
The Short Answer
Google Ads can technically start driving clicks within 24 to 48 hours of your ads being approved, but reliable, profitable performance usually takes 8 to 12 weeks. Meta Ads (Facebook and Instagram) exits its initial learning phase after roughly 50 optimisation events within a 7 day window, which for most small to mid sized trade businesses takes anywhere from one to three weeks. In both cases, early activity is not the same as working. It just means the platform has started collecting data.
Why Paid Ads Do Not Work Instantly
Both Google and Meta run on machine learning systems that need real world data before they can optimise properly. When you launch a new campaign, the algorithm does not yet know which searches, audiences, placements or times of day convert best for your business. It has to test, gather signals and adjust, and that process takes time regardless of budget.
This is why a campaign that looks patchy in week one is not necessarily broken. It is usually just early. Making big changes to budget, targeting or bidding during this window can reset the learning process and push your timeline back even further, which is one of the most common mistakes we see trade businesses make when they manage ads themselves.
Google Ads Timeline: What to Expect
Day 1 to 2: Review and Approval
Google reviews most ads within one business day, though more complex reviews can take longer, particularly in regulated categories. Once approved, your ads can start showing impressions within hours and generating clicks within 24 to 48 hours.
Week 1 to 4: The Learning Phase
This early period is volatile. Google’s system is still gathering conversion data and testing keyword and audience combinations, so cost per click and cost per lead can swing around a fair bit. A 30 day window generally gives a more reliable read on performance than judging results after a handful of days.
Week 6 to 12: Optimisation and Stabilisation
Most agencies, including us, tell clients to give a Google Ads campaign at least 8 to 12 weeks before making a call on whether it is working. This is when enough conversion data has usually built up for bidding and targeting to stabilise, and for cost per lead to settle into a predictable range.
Month 4 and Beyond: Maturity
A genuinely strong Google Ads account is usually still improving 4 to 12 months in, as underperforming keywords get cut, high performing ones get more budget, and landing pages get refined based on real conversion data. Paid search is a compounding channel, not a one off switch you flip.
Meta Ads Timeline: What to Expect
Day 1 to 3: Review and Early Delivery
Meta’s ad review also targets around 24 hours, though in practice it often takes 48 to 72 hours, especially for new ad accounts. Delivery data starts accumulating during this review window, so the learning phase effectively begins before your ad is even fully live.
Week 1: The Learning Phase
Meta’s own guidance is that an ad set needs approximately 50 optimisation events, such as leads or purchases, within a 7 day rolling window to exit the learning phase. Until that threshold is hit, cost per result tends to be higher and less predictable, because the algorithm is still exploring which audience segments and placements convert. For a trade business with a modest daily budget, hitting 50 events in a week is not always realistic straight away, which is why some campaigns sit in a ‘learning limited’ state for longer.
Week 2 to 4: Stabilisation
Once an ad set clears the learning phase, delivery typically becomes more consistent and cost per result starts to settle. This is usually the point where creative testing becomes genuinely useful, because you are comparing performance on a level playing field rather than reacting to early noise.
Ongoing: Creative Fatigue and Refresh
Meta campaigns need more regular creative refreshes than Google Search campaigns, because the same audience sees the same ad repeatedly on social feeds. Performance can dip after several weeks simply because the creative has gone stale, not because the targeting is wrong.
Google Ads vs Meta Ads: The Key Difference
The core difference comes down to intent versus discovery. Google captures existing demand. Someone searching “emergency boiler repair near me” already wants what you offer, so Google Ads tends to produce faster, more direct enquiries once the account has enough data. Meta, by contrast, finds people who fit your ideal customer profile but were not necessarily looking for you that day, so it often needs more creative testing and a longer runway to build trust before it converts at scale.
In practice, Meta’s algorithm can technically settle faster than Google’s (roughly a week versus two to three months), but Google Search often produces higher intent leads sooner, because the person is already searching with buying intent. Neither platform is simply “faster” in a way that matters on its own. What matters is which one fits your ideal customer at each stage of their decision, which is exactly the kind of structure we build into every paid media campaign we run for trade businesses.
Signs Your Paid Ads Are Actually Working
Because early data is noisy, it helps to know what genuine progress looks like rather than watching cost per click in isolation.
Impressions and clicks arriving steadily without big day to day swings once you are past the first couple of weeks.
Cost per lead trending down, or at least flattening out, rather than climbing week on week.
Conversion tracking is firing correctly, so the platform actually has the data it needs to optimise. This is one of the most overlooked issues we find when auditing new client accounts.
Quality of enquiries improving, not just volume. A jump in form fills that never turn into jobs usually points to a targeting or messaging issue rather than a timeline issue.
When to Worry
If you have verified your tracking is accurate and you have given a Google Ads campaign a full 90 days, or a Meta campaign 4 to 6 weeks, with genuinely zero conversions, that is a real signal something needs to change. It could be the offer, the landing page, the targeting, or the account structure itself, rather than simply needing more time. This is usually where a proper account audit is worth more than another month of guessing.
Getting the Timeline Right From the Start
The businesses that get the most out of paid ads are the ones that set expectations correctly before launch, track the right metrics from day one, and resist the urge to tinker with campaigns every few days.

FAQs
How quickly can I expect leads from Google Ads?
Some businesses see their first enquiry within days, particularly for high intent local searches, but consistent lead flow usually takes 4 to 8 weeks as the algorithm gathers enough conversion data to optimise reliably. Give it at least 90 days before judging overall viability.
Why is my Meta ad stuck in “learning limited”?
This usually means your ad set is not generating enough optimisation events (around 50 per week) for Meta’s algorithm to exit the learning phase. Increasing your budget, broadening your targeting, or consolidating multiple ad sets into one can help it reach that threshold faster.
Should I pause my ads if I am not seeing results in the first week?
Generally no. Pausing and relaunching resets the learning phase on both platforms, which extends your timeline rather than shortening it. Unless there is an obvious error, such as broken tracking or a disapproved ad, it is usually better to let the first week or two run its course.
Do Google Ads or Meta Ads work faster for trade businesses?
Google Ads tends to produce quicker, higher intent enquiries because it captures people already searching for your service. Meta is better suited to building brand awareness and generating demand among people who are not actively searching yet, so it often needs a longer runway to prove its value.
How much budget do I need for Meta ads to exit the learning phase quickly?
As a rough guide, your daily budget needs to be high enough to generate around 50 optimisation events within 7 days. For a typical trade business optimising for leads, that often means a daily budget in the low hundreds of pounds, though it varies significantly by cost per lead and location.
